IXYS' MwT Subsidiary Introduces Three Microwave Monolithic ICs (MMICS), Ultra-Broadband Driver and Power Amplifiers.

SANTA CLARA, Calif. -- IXYS Corporation (Nasdaq: IXYS) announced that its wholly owned subsidiary, Microwave Technology Inc. (MwT), introduced a family of three new MMIC chips (MMA-0220xxx series). These 2-20 GHz ultra-broadband MMIC distributed amplifier products are targeted at military and high frequency test instrumentation markets with excellent performance. The applications include Electronic Warfare Systems (EW), Electronic Counter Measures (ECM), EW threat simulator systems, radar, broadband buffer amplifier for frequency source and wideband test equipment, etc.

The first MMIC chip in the family, MMA-022020B, is a broadband medium power driver with output power of 22.5 dBm at 1dB gain compression point. The typical small signal gain is 8dB across the extended frequency band of 1 to 22 GHz. The bias conditions are 7 V and 220 mA. The second chip, MMA-022025B, is a broadband medium power amplifier with output power of 27 dBm at 1dB gain compression point. The typical small signal gain is 7.5 dB across the extended frequency band of 1 to 26 GHz. The bias conditions are 8V and 290 mA. The third chip, MMA-022030B, is a broadband power amplifier with output power of 29 dBm at 2dB gain compression point (28 dBm from 17 GHz to 20 GHz). The typical small signal gain is 6.5 dB across the frequency band. The bias conditions are 9V and 490 mA.

"These ultra broadband MMIC chips demonstrated our excellent MMIC product capabilities and provide customers high performance and user friendly solutions for various applications," said Dr. Greg Zhou, General Manager of MwT. "All three chips are fully matched for input and output and have good gain flatness. The overall gain is over 20 dB when the three chips are cascaded. They are realized by advanced pHEMT technology with excellent reliability and robustness. The MTTF of all three chips is over 1E6 hours for ambient temperature at 85 degrees Celsius, making them also suitable for Space and Hi-Rel applications."

Please download data sheets for all three parts for detailed technical information from MwT website www.mwtinc.com and contact MwT sales/marketing for pricing and sample request. Sample quantities of each MMIC are available now and production will start in August 2007. For more information send e-mail to [e-mail] or [e-mail]
